High-power-density sputtering of industrial-scale targets: Case study of (Al,Cr)N

Materials & Design
Large-scale sputter-deposition of hard protective coatings has not been prevalent as the large dimensions of the industrial targets posed an enormous technological challenge: only relatively low power (and plasma) densities could be achieved, resulting ...

Minimal-surface-based multiphase metamaterials with highly variable stiffness

Materials & Design
Variable-stiffness materials have a unique ability to change their stiffness reversibly in response to external stimuli or conditions. However, achieving ultrahigh stiffness change is often constrained by the geometric organization of the microstructures
